摘要： An embodiment of an apparatus to authenticate a sequence of video frames includes a process to choose intra-frames of the sequence and sample DC components thereof to produce a set of test fingerprints. To reduce a dimensionality of the test fingerprints, the DC components of the chosen intra-frames are multiplied by a projection matrix formed of eigenvectors associated with the larger eigenvalues of a covariance matrix for a library of frames. The projected test fingerprints are compared against a reference set of fingerprints for authentication. Time-stamp spacings of the chosen intra-frames are determined, and these spacings are employed to select candidate frames for authentication in the reference set of fingerprints.

A wireless transmission method based on an estimation of maximum multi-paths delay, comprising: a communication apparatus involved in wireless communication estimates the maximum multi-paths delay of a currently received frame; the communication apparatus performs a quantization and coding on feedback information related with the estimated maximum multi-paths delay, and then sends the feedback information which has been subjected to the quantization and coding to an opposing communication apparatus which is in wireless communication with the communication apparatus; the opposing communication apparatus recovers the feedback information by demodulating and decoding the feedback information which has been subjected to the quantization and coding; the opposing communication apparatus performs an adaptive adjustment of wireless signals transmitted to the communication apparatus, based on the recovered feedback information. With this method, system parameters can be adaptively adjusted so as to that sufficiently improves the spectrum utilization efficiency of wireless resources (the throughput is increased by about 5%).

摘要： The detecting and monitoring of solid structure or phase transformation, such as those used for testing the formation of gas hydrates and their inhibition by chemical additives may be conducted in a multi-test assembly of laboratory bench scale loops. The test loop contains a fluid that includes water and hydrate-forming guest molecules such as methane, ethane, carbon dioxide and the like at hydrate-forming conditions of low temperature and high pressure. A small bit or “pig” may be circulated through the test loop at variable speeds to circulate the fluid in the loop. The pig may be moved or impelled through the test loop remotely. The exterior of the pig and/or the interior of the loop may be smooth and/or have a friction-reducing coating thereon to facilitate movement of the pig through the loop. The formation of hydrates may be monitored with consistent and reproducible results.
